In all cases, upon return +.I reason_rtrn +contains a status value indicating success or the type of failure. If +.I major_in_out +and +.I minor_in_out +are not NULL, +.I XkbOpenDisplay +first calls +.I XkbLibraryVersion +to determine whether the client library is compatible, passing +it the values pointed to by +.I major_in_out and +.I minor_in_out. If the library is +incompatible, +.I XkbOpenDisplay backfills +.I major_in_out +and +.I minor_in_out +with the +major and minor extension versions of the library being used and returns NULL. +If the library is compatible, +.I XkbOpenDisplay +next calls +.I XOpenDisplay +with the +.I display_name. +If this fails, the function returns NULL. If successful, +.I XkbOpenDisplay +calls +.I XkbQueryExtension +and backfills the major and minor Xkb +server extension version numbers in +.I major_in_out and +.I minor_in_out. If the server +extension version is not compatible with the library extension version or if the +server extension is not present, +.I XkbOpenDisplay +closes the display and returns +NULL. When successful, the function returns the display connection. + +The possible values for reason_rtrn are: + +.IP \(bu 5 +XkbOD_BadLibraryVersion indicates XkbLibraryVersion returned False. +.IP \(bu 5 +XkbOD_ConnectionRefused indicates the display could not be opened. +.IP \(bu 5 +XkbOD_BadServerVersion indicates the library and the server have incompatible +extension versions. +.IP \(bu 5 +XkbOD_NonXkbServer indicates the extension is not present in the X server. +.IP \(bu 5 +XkbOD_Success indicates that the function succeeded. +.SH "RETURN VALUES" +.TP 15 +NULL +The +.I XkbOpenDisplay +function returns NULL if the library is incompatible. +.sp +.in 20 +The +.I XkbOpenDisplay +function returns NULL if the call to +.I XOpenDisplay +with the +.I display_name +fails. +.sp +.in 20 +The +.I XkbOpenDisplay +function returns NULL and closes the display if the server extension version is not +compatible with the library extension version or if the server extension is not present. +.SH DIAGNOSTICS +.TP 15 +.SM BadAccess +The Xkb extension has not been properly initialized +.SH "SEE ALSO" +.BR XkbLibraryVersion (__libmansuffix__), +.BR XkbQueryExtension (__libmansuffix__), +.BR XOpenDisplay (3X11) |
